[en] While indicating some characteristics of awarded projects, a first article outlines the asset represented by large thermal solar installations used for heat networks. A second article presents the first world thermal solar plant on trackers developed by the NewHeat company on the property of a paper mill (the so-produced energy is sold to the industrial): it should produce nearly 4.000 MWh/year. The operation and the financing process are briefly described. The next article outlines that a previous thermal French regulation (RT 2012) did not support the development of solar thermal in the building sector, but that the new energy regulation (RE 2020) could change the deal. It also indicates the elaboration process of this RE 2020 and requirements for each energy level and carbon. An article comments the development strategy implemented for heat networks by the Rouen metropole. This comprises conversion, extension or creation of such networks. Financing issues are also evoked. The last article addresses a call for projects on new emerging technologies (AAP NTE) in the field of renewable heat (production of renewable energy based on the use of solar energy, biomass, geothermal energy, and on the valorisation of unavoidable heat. SWAC systems (Sea Water Air Conditioning) and the warm water loop process are briefly presented

[en] A first article discusses the activity of the Heat Fund during 2020 by highlighting the increasing number of submitted files, indicating the distribution of energy sources (important role of wood in the industry), and commenting the possibility of accumulated aids. A second article comments the results of a study performed by the ADEME to assess the operation of ten different farm-based methanization units. The next article reports the commitment of members of a Sarl (Methalayou) who have been among the first to develop a methanization project with the support of their territory and a major role of renewable energies, and notably the evolution from co-generation to injection into the network. An article briefly evokes the content of a guide published by the ADEME and GrDF and aiming at giving a comprehensive and detailed overview of ways to finance a methanization project: loans, crowdfunding, private and public funds, subsidies, and so on. The last article presents the activity of an association gathering 26 farms to invest into a methanization unit fed by only manures from these farms

[en] A first article of this file about renewable heat proposes a commented assessment of the support brought in France by the Ademe through the Biomass Heat Fund in 2019 (level of biomass-based energy production, number of processed files, support amount). The second article more particularly comments the situation of the call for projects related to biomass, heat, industry, agriculture and office building (BCIAT) with some indications related to laureate projects (a paper mill using a biomass boiler, and an agri-food industrial site committed in the reduction of greenhouse gas emissions). The third article comments the development of a rural heat network supplied with biomass in a small commune (Corbie, Somme). The last article comments the choice by the Rouen metropolis of an innovative biomass boiler (a Danish staged combustion boiler which separates the different stages: drying, pyrolysis-gasification, combustion), and the associated development of a heat network which supplies several communes

[en] After an interview which discusses the favourable assessment of the Heat Fund operation in 2019 (evolution of numbers of projects, of new installations, of renewable and recoverable energy production), an article comments actions and investments undertaken by the Kimberly-Clark plant in Villey-Saint-Etienne to reduce its environmental impact, notably through the recovery of the unavoidable heat in its atmospheric releases. The next article presents an innovating platform designed as an outlet for the heat of an energetic valorisation centre, and as a supply of the heat network of the urban community of Dunkirk. A methanisation project involving 12 farms in Saone-et-Loire is presented, and then the development by Gazteam Energie of a methanisation unit based on the continuous dry process. Then, in order to illustrate the development of the solar thermal sector, an article outlines the better support awarded to this sector by the Heat Fund, and another one outlines that a call for projects in 2019 concerned large thermal installations. The practice of long-term leasing of solar thermal installations by Eklo Invest in the Oleron island is then commented, and the example of a solar thermal installation for domestic water heating in a social housing building in Marseille is presented

[en] A first article outlines the remarkable development of the use of wood energy in the French industry as it is now supported by the Heat Fund and by the Industry Decarbonation Fund. A table notably indicates an assessment of the Heat Fund for 2020 (energy production by various different sectors and different energy sources). A second article sheds a light on practices of some sawmills which (after a call for projects by the ADEME) are valorising wood wastes in boilers: this practice results in turnover increase and activity diversification. Another example of the use of biomass, supported by the Industry Decarbonation Fund, is presented with the replacement of coal by forestry wood chips in dehydration ovens. The successful deployment of a heat network in the city of Pau is commented, notably for its territorial dimension, and its even too great public success. Another example of biomass-based heat network is presented (in the Le Grand Luce commune) which notably supplies individual housing. The last article evokes the example of a sawmill which invested in a wood-fired boiler for the production of thermally processed and dried wood products to be exported

[en] The enthusiasm for green mobility arouses a boom of electric vehicles, but the stakes go beyond the erasure of the thermal engine: this mutation can serve the integration of the wind and the photovoltaic for the energy transition. The 'green electricity for vehicles' theme is deployed at the same pace as the sale of electric vehicles, but raises questions on the energy or ethical plane, because electric power is sometimes not as 'green' as announced. Another article addresses solar recharge terminals; the service rendered to the network is important, especially if the terminals are controllable. The promises of vehicle-to-grid (V2G technologies) can transform electric cars into intelligent storage systems, a solution that could overwrite the intermittency of renewable energies and bring flexibility to the network. Some start-ups enterprises decided to take advantage of these features to imagine vehicles recharging thanks to the sun; some even claim the zero recharge, for 100 pc solar cars. In terms of maritime and river transport, projects aim to associate electric propulsion and green energy production. Several examples are given: in Auvergne-Rhone-Alpes, the Hympulsion Company, which combines public and private capital, develops a project of 20 stations and 1,200 vehicles. The Metropole of Montpellier launched 'Mobilite Hydrogene' with a unit of production that will supply buses by a photovoltaic plant. In Vendee, green hydrogen is produced with electricity by a wind farm for a hundred heavy vehicles. In Strasbourg, the hydrogen comes out of the wood: now 'zone at low emissions', the territory of Strasbourg must become exemplary in terms of mobility. Hydrogen will help it, thanks in particular to a production process using biomass. Solar aircraft: Helioclim offers an innovative solar air conditioning solution. Based on an absorption machine, it benefits from the power of concentration thermal solar collectors

Derriere la voiture electrique, les energies renouvelables: L'engouement pour la mobilite verte suscite un boum des vehicules electriques. Mais l'enjeu depasse l'effacement du moteur thermique: cette mutation peut servir l'integration de l'eolien et du photovoltaique qu'appelle la transition energetique. Une electricite verte pour les vehicules: Vision panoramique sur les offres d'electricite renouvelable dediees a la mobilite en France. La thematique se deploie au meme rythme que la vente de vehicules electriques, mais souleve des questionnements sur le plan energetique ou ethique, car l'electricite n'est parfois pas aussi 'verte' qu'affichee sur le pare-brise du consommateur. Les bornes de recharge solaires: Partout en France sont menees des experimentations d'alimentation de bornes de recharge pour vehicules electriques par de l'energie solaire. Le service rendu au reseau est important, notamment si les bornes sont pilotables. Les promesses du vehicle-to-grid: Les technologies dites vehicle to grid ou V2G (vehicule connecte au reseau) permettent de transformer les voitures electriques en systemes de stockage intelligents. Une solution qui pourrait pallier l'intermittence des energies renouvelables et apporter de la flexibilite au reseau. Le solaire s'integre aux vehicules: Voitures et camions sont la plupart du temps en plein air et offrent des surfaces pouvant integrer des cellules solaires. Quelques start-up ont decide de tirer parti de ces caracteristiques pour imaginer des vehicules se rechargeant grace au soleil. Certains revendiquent meme le zero recharge, pour des voitures 100 % solaires. Voguer a l'electricite renouvelable: En matiere de transport maritime et fluvial, des projets visent a associer propulsion electrique et production d'energie verte. Zero Emission Valley, l'hydrogene vert pour la mobilite: En Auvergne-Rhone-Alpes, la societe Hympulsion, qui associe des capitaux publics et prives, developpe un projet d'installations de 20 stations et 1 200 vehicules. Pour deployer l'hydrogene renouvelable a grande echelle, elle doit repondre a des enjeux de massification. A Montpellier, l'hydrogene se fait une place au soleil: Avec le projet MH2, la Metropole de Montpellier opte pour la mobilite hydrogene, sans pour autant oublier ses racines ensoleillees: implantee localement, l'unite de production qui approvisionnera les nouveaux bus sera alimentee par une centrale photovoltaique. En Vendee, l'hydrogene a le vent dans le dos: En juillet, la premiere unite de production industrielle d'hydrogene vert, alimentee en electricite par un parc eolien, sera mise en service a Bouin, en Vendee. Elle fournira a terme le carburant d'une centaine de vehicules lourds. Le modele, qui fait deja des petits, porte de grandes ambitions. A Strasbourg, l'hydrogene sort du bois: Desormais 'zone a faibles emissions', le territoire de Strasbourg se doit de devenir exemplaire en matiere de mobilite. L'hydrogene l'y aidera, grace notamment a un procede de production utilisant la biomasse. Avions solaires - embarquement imminent: Helioclim propose une solution de climatisation solaire innovante. Basee sur une machine a absorption, celle-ci beneficie de la puissance des capteurs solaires thermiques a concentrationJournal
